SWITCH-STAND.

SPECIFICATION forming part of Letters Patent No. 760,044, dated May 17, 1904.

Application filed February 25, 1904. Serial lilo. 195,270. (No model.)

To all whom it may concern: i Be it known that we, J AMES Gr. WA'rrJRs'roN and IVIA'IT SMITH, citizens of the United States,

residing at Scanlon, in the county of Carlton and State of Minnesota, have invented certain new and useful Improvements in Switch- Stands; and we do declare the following to be and simplify the construction and operation of devices of this character and to thereby render them more eihcient and durable in use and less expensive to manufacture.

lever, taken on the line y y of Fig. 1.

Referring to the drawings by numeral, 1 denotes a rectangular metallic base adapted to be secured by spikes or the like to ties, stringers, or any other suitable foundation along the side of a railway-track adjacent to the switch to be operated. Disposed longitudinally upon said base 1 is a guide-casing 2, having a central cylindrical here or opening 3 extending longitudinally through the same and having the cylindrical portion 4: of a switch operating bar 5 slidably mounted The said portion 1 of the bar 5 projects into one end of the casing 2, which has its other end closed by a screw-plug 6, and the enlarged portion 7 of said bar 5 has its outer end slotted or bifurcated, as at 8, to per- 13, one of the bifurcated or forked ends of which is pivoted bya pin 14 to a lug 15 upon the enlarged portion 7 of the bar 5, and the opposite bifurcated end of said rod 13 straddles thelower portion of the lever 9, to which it is adjustably pivoted by a pin 16, adapted to be passed through alining openings in said forked end of said rod and through one of a series of openings 17 formed insaid lever. The lever swings in an opening or slot formed in a segmental or arc-shaped rack-frame 18, projecting vertically from the casing 2. The upper edges of the sides 19 of said frame 18 are formed with notchesQO, adapted to be engaged by a pawl 21, which holds said bar in an adjusted position. Said pawl is slidably mounted upon the lever by forming the same with a slot 22, through which a bolt 23 upon the lever projects, and said pawl is normally held seated in said notches by a coil-spring 24, confined between projections upon the upper end of said pawl and upon alug25 formed on said lever. In order to retract said pawl, a handpiece 26 is pivoted, as at 27, adjacent to the upper end of the lever and connected to said pawl by parallel links 28, disposed on each side of said lever and adapted to assist in guiding said pawl. It will be seen that by operating said handpiece the links 28 will draw upon the "pawl and raise it against the tension of the spring 2 1. In order to lock said pawl against movement, and hence to lock the entire apparatus, a lug 29 is provided upon said lever and is formed with an opening or aperture 30, adapted to register or aline with an opening 31 formed in one of the links 28, so that a padlock or other looking device may be inserted in said openings to lock said parts against movement;

In order to operate the usual target-signal 32, secured upon the upper end of a vertical shaft 34, mounted in bearings 35 and 36 upon said frame 18 and base 1, we secure to said shaft a gear or pinion 37, which projects through a slot or opening 38, formed in one of the sides 19 of the frame 18, and which is in mesh with a rack 89, formed or secured upon the said connecting rod or link 13. It will be seen that when said lever is shifted the movement of the connecting-rod will shift the switch-bar 5, and its rack 39 will at the same time turn the gear 37, which will rotate the shaft 34, and hence operate the targetsignal.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

v1. In a switch-stand, the combination of a base having a guide-casing, a switch-operating bar slidably mounted in said casing an" link for actuating said target or signal device when said lever is operated, substantially as described.

3. In a switch-stand, the combination of a base having a guide-casing, a switch-operating bar slidably mounted in said casing, a pivotally-mounted operating-lever, a link or rod connecting said bar and said lever, a target-shaft, a gear upon said shaft, and a rack upon said link adapted to actuate said gear when said lever is operated, substantially as described.

4. In a switch-stand, the combination of a base having a guide-casing, a switch-operating bar slidably mounted in said casing, a hand-lever pivoted upon said casing, a link connecting said bar and lever, a segmental rack upon said casing, a spring-actuated pawl upon said lever adapted to coact with said segmental rack, a handpiece upon said lever for retracting said pawl, a' vertical targetshaft, a gear upon said shaft, and a rack upon said connecting-link in mesh'with said gear, substantially as described.,' ,1 p

5. In a switch-stand,thefiombination of a switch-operating hand lever having an apertured lug, a pawl up said lever, a handpiece, upon said lever, and links connecting said handpiece and fsaid pawl, one of said JAMES G. WATERSTON. MATT SMITH.
